Danfoss PVG 16 - Test Report

Closed center PVPV with PPRV
The Closed Center PVPV inlet with integrated pilot pressure reduction valve (PPRV) is intended for use
with variable displacement pumps in applications where a valve group with electro-hydraulic or
hydraulically controlled work sections is desired.
The Closed Center PVPV with PPRV features:
•
Optional shock/anti-cavitation valve facility (PVLP)
•
Threaded ports for P/T/LS and M measuring gauge
•
Integrated pilot pressure reducing valve (PPRV) for PVE or PVH/PVHC
